Kenyan investigators gather at a police station in the capital Nairobi where earlier a man who police say confessed to murdering 42 women escaped from a police cell, along with a dozen other detainees. Collins Jumaisi, 33, described by police as a "vampire, a psychopath", was arrested last month after the horrific discovery of mutilated bodies in a garbage dump in a slum in the Kenyan capital.
